To all fur/7101i?, it muy concern/f ie it known th at l, Jarras A. Davis, citizen of the United tltates, residing at 1Washington, District of Columbia, have invented certain new and useful .improvements in ntislipping Attachments for liorseshoes, of which the following is a specification.

My iraient-ion relares to horse shoes and particularly to a calli supporting attachment for horse shoes designed when used to prevent the slipping of the shoe upon icy pavements or roads.

The primary object of my invention is the provision of a simple, cheap and effective device whereby the ealks may be removably supported upon a horse shoe, and a further object in this connection is to so mount the calks that they may be readily removed and replaced when desired.

It further obj eet is to so construct the attaclnnent that it may be tightened upon the horse shoe and when so tightened will not act either to expand or contract the shoe and will not therefore tend to laterally compress or expand the horses hoof.

A further object is to so form the attachment that the tightening strain will be exerted longitudinally along` the shoe and not transversely thereof.

It further object is to so form the attachment that it will not be forced against the frog` when in position.

nt fini-ther objectis to so form the attachment that it will conform to the shape of the hoof and thus be adjustable to hoofs which are more or less irregular in shape.

My invention is illustrated in the aecompanying drawings, wherein, i lligure 1 'an underside plan view of a horse shoe with my attaclnnent applied thereto. liig. 2 is a side elevationof the attachment applied to a hoof. Fig. d is a transverse vertical. section through the attachment on the line SMS of Fig. 1. Fig. Il a transverse section on the line i-f-lof llig. 1. Fig. 5 a side elevation of one of the calles detaehed. l*1 ig. t3 is a cross seetional view through the nut 12, the cotter pin and the bolt 9. Fig. l a side elevation 'ofv one of the ralks of my horseshoe detached from the shoe itself.

Referring to these drawings designates a horse shoe of any ordinary or usual form and provided with heel ealks o.

'lt/ly improved attachment includes clamping members 2 having angularly bent terbetween the members cured by means of pins ward through a plate 5, through the meinbers 2 and through the plate 5 and are provided at their upper perfor-ations for the reception of Cotter pins lt will be seen that the flange minal ends 3 which are curved slightly inward so as to engage with the hoof, as illustrated in Fig. 2. Each of these members Z carries upon it ealks f1, which ealks are mounted in a manner to be hereinafter stated. The members 2 are pivotally connected to a plate 5, which plate has an angularly bent edge G. rlhe pivotal connection 2 and the plate 5 is se- 7 which extend upends with transverse S. llfhe lower ends of the pins 7 are headed. G on the plate 5 forms a stop, limiting to some extent, the outward movement of Athe members 2.

Extending rearward from the plate 5 and preferably formed as the part of the plate is a tightening rod 9 whose rear end is screw threaded as at 10. This rear end is preferably slotted as at 11. A wing nut 12 engages the screw threaded portion 10 and this nut is perforated, as illustrated in Fin'. with. passages extending. at right angles, these passages being designated 13. A cotter pin lll is adapted to be inserted through these passages for the purpose of holding the nut in any adjusted position.

,l'ioosely mounted upon the tightening rod 9 a yoke 15, this yoke, as illustrated in Fig. l, being formed of upper and lower plates 1G and 17. The tightening rod 9 passes loosely between these plates 1G and 17 so that the tightening rod may be laterally shifted to one side or the other of a median line, as illustrated in dotted lines in Fig. 1.

livotally connected to each end of the yoke 15 are links 1S which carry rearwardly extending lj-shaped members or loops designated 19 which extend over the heel ealks L when the attachment is iin. place, as illustrated in ligs. 1 and 2. The rea-r end of each loop 1,9 closed at its top by a plate S20. This plate, when the loop is in position, extcmls between the heel oit the shoe and the adjacent portion of the hoof, prevent-ing any depression of the loop relative to the adjacent end of the shoe. Preferably each loop 19 is made integral with the link which connects the loop with the yoke 15 and preferably arch link formed as illustrated in ifig. 2%, that is, with upper and lower memhers 18 and 15% The member 155" extends Vas to present a flat bearing face to the mem- In attaching my device to a horse shoe the clamping members 2 are first engaged with the shoe on each side of the toe and loops 19 are disposed over the heel of the shoe in the manner shown in Fig. 1. The loops 19 and the members 2 being pivotally connected to the tightening rod 9 and to the yoke 15, adjust themselves to any peculiar form of shoe. The nut 12 is then tightened up, drawing' the inner ends of the clamping members 2 rearward and drawing the loops 19 forward. rIhe strain of the tightening rod 9 is exerted longitudinally upon the shoe and not transversely and hence there is no transverse strain placed upon the shoe which would tend to compress the shoe or expand the same, at the same time the clamping action acts to force the inwardly turned ends of the jaws 3 into engagement with the hoof so that the attachment cannot be pulled oft' at its forward end. The plates 2O prevent the rear ends of the attachment from being' disengaged from the shoe.

If all hoofs were regular in form, it would not be necessary that the clamping rod 9 should be laterally shiftable, but I find in practice, that it is necessary to make provision for irregularities in contour, and this is the reason why I so form the yoke 15, that the clamping rod 9 may have a lateral adjustability relative to the yoke. An attachment which is not adjustable in this regard can only be used on perfectly regular hoofs, but I have found in practice, that my device is capable of being used on hoofs which greatly vary from the regular form. It will also be noted that the heel calks 22 are held in proper position, transverse to the horns of the shoe and that these heel calks cannot get out of place. Furthermore itwill be seen that these heel calks cannot rotate when the attachment is in place on a shoe for the reason that the base of each calk will be shoe.

lVhile I have illustrated what I deem to be the best form of my invention and one which I have found to be thoroughly effective in practices I wish it understood that I do not wish to be limited to the details illustrated, but that I may vary the construction in many ways without departing from the spirit of the invention.

lVhile I have shown the calks as being triangular in form, it will, of course, be understood that I may use calks having fiat bearing faces instead of sharp bearing faces, and that these flat calks may be interchangeable with the sharp edged calks. These fiat calks may be used for ordinary work and may be used for the purpose of lengthening the life of the shoe. Thus when the shoe becomes old and thin, my attachment may be applied to the shoe and inasmuch as all wear will be borne by the calks of the atoutwardly from the side of the loop 19 at its upper edge, while the member 18a extends outwardly from the side of the loop 19 at its lower edge, the members 1S and 18a converging and the ends of said members either being welded together or pressed together and inserted between the members 1G and 1T of the yoke. To pivotally connect the links 18 to the yoke, I provide vertically disposed pins 20 headed at their lower ends and perforated at their upper ends for the passage of cotter pins 21. This construction permits the links to be detached from the yoke.

As before observed the loops 19 are U- shaped and disposed between the open end of each loop is a triangular calk Each loop 19 is slightly wider than the heel end of the slice, and hence fits against the sides of the horse shoe. The calk 22 is disposed slightly below the upper edges of the forwardly eX- tending ends of the corresponding loop, so that the upper face of the calk will be held firmly against the bottom face of the shoe. Each heel calk 22 is preferably held in place by a pin 23 which extends through the side plates of the loop 19, the end of Athe pin being formed with a perforation for the reception of a cotter pin It will be seen that the purpose of forming the links 1S with converging portions as illustrated in Fig. 3 is to accommodate the pin 21 and permit the pin to be readily removed or replaced.

The calk 22 as before stated is triangular in form so as to provide three bearing faces and three cutting edges and it is also preferably provided with three transverse perforations 25, through any one of which the pin 23 may pass. These perforations 25 are so disposed that when the pin 23 is passed through one of the perforations 25 there will be a horizontal bearing face and a downwardly extending cutting edge. By providing three perforations 25 it is possible to remove a worn calk, rotate the calk and replace it so as to present an unworn cutting edge to the ground. It is also possible to remove the calk entirely and replace it by an entirely new calk. The front calks 4t may be riveted to the members 2 or may have screw threaded engagement with these members but preferably they are supported by providing downwardly projecting lugs 26 on each of the members 2 and providing a transverse pin 27 which extends through these lugs and through the calk and which is held in place by a cotter pin 28. Each calk et is preferably triangular in section so ber 2 and a sharp edge to the ground and each calk is preferably provided with three perforations 29 through any one of which the pin 27 may pass, thus permitting the calk to be rotated so as to present a new cutting edge to the ground when the old cutting edge is worn away.

pressed i'irmly against the face of theA Cre tachment and not by the shoe, the old shoe will last comparatively a long while.

It will be seen that the attachment may be readily applied and readily detached, and that thus it is capable of being used under a variety of circumstances, and that thus the horses may be sharp shod whenever neeess-ary without the necessity of having the sharp calks remain in place when there is no need for them.

As before stated, my attachment, by reason of its peculiar structure, is adapted to be used where the shape of the hoof is irregular. lt is also adapted to be used where one horn of the shoe is longer than the other. Horses are often shed in this manner and my attachment is also so constructed that it will adapt itself to any peculiar formation of the shoe.

rlhis attachment may remain attached to the hoof for an indefinite period, without injury to the hoof in any manner and may be used simply for the purpose of taking all wear from the shoe proper'. The body of the attachment may be used for an indefinite period and. as all wear comes upon the calks, it will only be necessary to replace the calks when worn with new calks which can be readily done without taking the attachment from the hoof.

ln order to prevent snow from balling up in the horses hoof, I provide a relatively wide iiat spring designated 30. The ends of this spring are rebent at 31 and as shown in dotted lines in Fi Q, the relic-Bied ends of `the spring being attached to the plates 16 and 5a by means of rivets or like devices. This spring 30 extends beneath the tightening rod 9 but does not project down as far as the points of the calksl and 22. The rebent ends permit the sjnfing1 to be flexed and when the pressure upon the hoof is released, the spring will return to its original form throwing out any ball. which may have accumulated on the hoof.
